The U.S. House of Representatives on Monday passed the Duck Stamp Act of 2014, which would increase the cost of a federal duck stamp from $15 to $25.

The last time the price of the duck stamp increased was in 1991, and Ducks Unlimited is in favor of the legislation.

“Ducks Unlimited strongly supports this effort to increase the conservation impact of the federal duck stamp,” said Dale Hall, CEO of DU. “The additional duck stamp funding provided by waterfowl hunters and other conservationists will not only conserve critical waterfowl habitat, but will also help ensure the future of our waterfowling traditions.”

According to a DU press release, the Duck Stamp Act of 2014 would build on the program’s long tradition of helping to fund conservation of vital waterfowl habitat across American, especially in the Prairie Pothole Region.

“We would like to thank members of the House for their strong showing of support in passing the Duck Stamp Act of 2014,” said Katie Murtha, DU’s chief policy officer. “Now on to the Senate, where we anticipate having the same showing of support for this much-needed legislation. DU’s goal is to have the Duck Stamp Act of 2014 signed into law by the end of the year. The time is now.”

Since the federal duck stamp’s introduction in 1934, it has raised more than $750 million and has conserved more than 6 million acres of waterfowl habitat, the release states.

The Senate is expected to take up the legislation sometime in the next few weeks.
